Thanks @sameer.

But if rising slope then maximum distance measured only 15 meters am I right?

staff readings visible for staff height of 2.5m so distance is 2.5x10 = 25m.

Avshesh said: 8 years ago

Staff visible= 4-1.5=2.5m,
Site=2.5/(1/10),
= 2.5x10,
= 25m.

Here, 2.5 * 10 = 25.

The Hi is 1.5m so when and staff 4m.
The reading will be 2.5m on staff on plane. The slope being 1 in 10.
2.5 * 10 = 25 on down slope.

The instrument height of 1.5m, staff height 4m so 4 - 1.5 = 2.5m.
